So the fibreglass didn't break at all, just the epoxy broke? Which explains why you got about 200 MPA rather than 3400MPA which is the tensile stress of the fibre.

There were a lot of concepts related to rheology I was struggling to piece together. Thank you for making this so clear.

Sir truly your way of explaining things are very easy to understand, thank you sir.

Respected Sir, Which book can we read the correct explanation of all the lubrication regimes with real world examples that also give detailed explanation about the curve? Kindly tell

Thank for the great video! Can someone explain equation 4.49 (32:40)? I made average strength calculations and couldn't get this exact expression.

Plus sir I want to learn what is the best base oil for engine oil

How equal will the elastic moduli be obtained using the direct tension or compression method and ultrasonic bulk wave through transmission measurements?

For tension coupon tests of GFRP, do we have to conduct test on lamina(single ply) or laminates (number of plies) ??

Very clear explanation and give a vivid example to show the complex concept to understand

Very informative understandable ....need more videos like this from u sir

A nice clear explanation of composite modulus and strength. Thank you.

How to derive the equation for loss modulus / storage modulus in terms of relaxation time and shear constant only

why UA-cam thought that this lecturer is speaking Hindi, while he spoke English. lol

Respected Sir, if possible please make a video explaining how different load acts on different types of bearings through Free Body Diagrams. Although it is written in different books that bearings take up radial, axial or combined radial and axial loads but understanding by mere reading the book becomes difficult specially how to visualise the loads acting on the bearings and why a particular type of bearing is suitable for a particular load category 🙏🙏

Really nice vedio for all students who interested in design field thank u sir.. await for next vedio..

Great video, thanks for the information

Hello sir, i am using an additive to my mineral 15w40 engine oil and this additive contains the long chain chlorinated olefin. I am using this additive since the end of the 90's without any problems. Is it true that the Chlorinated Olefin WILL corrode the engine regardless of the additive mix? The additive is resitant from -50 to 315 degrees celcius. Thank you. Rob

what is the Influence of an elevated temperature on tensile strength of glass fiber- reinforced polymer composites

Thanks for sharing knowledge

Thanks a lot

Very well explained, 👍 Can you please share the details of the book that you are following for these! Thank You.

Great video and great explanation

Please make a video for generalized maxwell model and implementation in ANSYS Workbench

Very well explained. Thank you.

Thank you very much Sir. But i would like to know about that how the viscosity of yogurt is tested.

I think it would have been more durable if you had also applied the vacuum process. The vacuum process both eliminates air bubbles and allows the epoxy to penetrate into the bamboo.(Of course, I have no idea how much bamboo absorbs epoxy, for lamination with epoxy, especially resin-free tree species are selected and treated with epoxy.)

Thank you so much for the knowledge, I'll be writing in a few days and I didn't understand what i was readying but this unlocked alot of blockage.

Hi Prof., can you provide some insight on how friction reduces when speed increases from mixed to EHL? Also, share thoughts on the film formation mechanism in the EHL region. Can EHL be applicable to flat-on-flat contacts?

Thanks so much. Hardness has been defined as resistance to plastic deformation. That's somehow similar to stiffness which is resistance to elastic deformation. My question is: is hardness analogous to stiffness, is it a rough equivalence of stiffness in the plastic region? I'm asking this in the hope that there's a way for me to make sense of hardness using the stress strain curve even though tensile test doesn't measure hardness. I keep wondering about that given that stiffness and hardness have the same unit and similar definitions. Would love to get your thoughts. Thanks

sir mera selectioin mechanical ke baad ho nahi raha kyuki cocept koi samaj hi nahi aa rhe kya karu sir 8 saal ho gaye

Sir, why don’t you use some better marker pens which can leave legible impression on the white board?

Very informative 🎉🎉 thanks

Hello, Thank you for the detailed video. Could you also explain how storage modulus is related to Young's modulus, if any? I have seen people using these alternatively. But these are two different properties. Isnt it?

thanks for such a nice video. 👍

Don’t use sealant 😊

Thank you

Thank you sir.

Thank you for your video. I have a question about this model. Is the JKR formula only applicable to the contact between spheres?

ممكن رقم تواصل

Thank you so much for this video, really helpful. I was wondering what formula for the friction coefficient can we use. in case i want to compare an experimental results curve with another theoretical curve?

What's fracture stress?

I'm a polymer engineering student and i want to say thank you for this video. It was great and I learned a lot from you❤️ thank you very much sir

Hello my project is on basalt fiber reinforced composites do i have to use the same ASTM standards for my test piece

Very informative. For viscosity values shown in the table, should we exclude the measurement at point 1 as it gives a totally different value from points 2 to 20?

Where i contact you regarding this testing i want to ask my query

Kudos👌 excellent describing. easy to understand

thanks

Thank you sir for this great video, it is really helpful and full of valuable information.. I do have one question for your kind input; Can you tell which of the two fiber deformation processes, i.e. whether fiber pull out or the fiber fracture, will consume more energy and results in higher toughness composite? Thank you again

Thanks for the video prof. I am recently starting a Master Thesis on Rheologie examination using very high shear rates, i am wondering the career prospects in the field, Will I be satisfied on this aspect ?

Thanks
